ionic liquid Enhanced Oil Recovery in sand pack columns
Fuel, 2014Co-Authors: Jorge F. B. Pereira, Rita Costa, Neusa Foios, Joao A P CoutinhoAbstract:Studies on the ionic liquids (ILs) for Chemical Enhanced Oil Recovery (CEOR) processes are limited. This work aims at fulfilling a gap in the research on IL-based CEOR processes (hereby designated by IL-EOR), showing the possibility to use the ILs as an alternative to the conventional chemicals widely studied for this purpose. Results application of ionic liquids are here reported, for the first time, on IL-EOR at Lab scale using a sand-pack column model. A 2 wt% aqueous solution of 1-ethyl-3-methylimidazolium tosylate ([C2mim][OTs]) was used to recover an aromatic Oil. The results show that a flooding processes using only 4 pore volumes (PV) could recover 65.7% (±1.0) of the Oil in place, almost the double of what was recovered with a brine solution (NaCl, 2 wt%). These preliminary results, requiring further optimization of the IL characteristics and concentration, and other process parameters, suggest that water-flooding with aqueous solutions of ILs can contribute to enhance the Oil Recovery in mature reservoirs.

synthesis and characterization of a new polymeric surfactant for chemical Enhanced Oil Recovery
Korean Journal of Chemical Engineering, 2016Co-Authors: K R Babu, V K Saxena, Nilanjan Pal, Ajay MandalAbstract:Chemical Enhanced Oil Recovery methods are field proven techniques that improve efficiency and effectiveness of Oil Recovery. We have synthesized polymeric surfactant from vegetable Oil (castor Oil) for application in chemical Enhanced Oil Recovery. First, an eco-friendly surfactant, sodium methyl ester sulfonate (SMES) was synthesized from castor Oil, and then the polymeric surfactant (PMES) was produced by graft co-polymerization reaction using different surfactant to acrylamide ratios. The synthesized PMES was characterized by FTIR, FE-SEM, EDX, TGA, DLS analysis. The performance of PMES as a chemical agent for Enhanced Oil Recovery was studied by measuring the interfacial tension (IFT) between crude Oil and PMES solution, rheological behavior and contact angle against sandstone surface. Addition of sodium chloride in PMES solution reduced the IFT to an ultra-low value (2.0×10-3mN/m). Core flooding experiments were conducted in sandpack system, and 26.5%, 27.8% and 29.1% additional Recovery of original Oil in place (OOIP) was obtained for 0.5, 0.6 and 0.7mass% of PMES solutions, respectively, after conventional water flooding.

studies on interfacial tension and contact angle of synthesized surfactant and polymeric from castor Oil for Enhanced Oil Recovery
Applied Surface Science, 2015Co-Authors: Keshak Babu, Achinta Bera, V K Saxena, Ajay MandalAbstract:Abstract New synthesized polymeric surfactants have immensely attracted the researchers for further development of chemical Enhanced Oil Recovery method particularly in surfactant flooding. Contact angle and interfacial tension measurement tests are the effective ways to identify proper chemicals/surfactants for Enhanced Oil Recovery by chemical/surfactant flooding. In the present study a new polymeric surfactant was synthesized from pre-synthesized sodium methyl ester sulfonate (surfactant) and acrylamide for application in chemical Enhanced Oil Recovery. The synthesized surfactant and polymeric surfactant were used to measure interfacial tension between their aqueous phase and crude Oil phase to investigate the efficiency of the surfactants in reduction of interfacial tension. The synthesized polymeric surfactant has also ability to control the mobility because of its viscous nature in aqueous solution. Contact angles of solid-crude Oil–surfactant interface were also measured to study the effect of the synthesized surfactant and polymeric surfactant on wettability alteration mechanism. Synergistic effect was studied by using NaCl and synthesized surfactants on interfacial tension. Dynamic interfacial tensions of the surfactant and polymeric surfactant solutions with crude Oil were measured at different NaCl concentrations. Interfacial tension was found to be lowered up to 10 −2 to 10 −3 mN/m which is effective for Oil Recovery. Measurement of contact angle indicates the wettability change of the quartz surface. Comparative studies on efficiencies of synthesized sodium methyl ester sulfonate surfactant and polymeric surfactant were also carried out with respect to interfacial tension reduction and contact angle change.

synthesis and characterization o f sodium methyl ester sulfonate for chemically Enhanced Oil Recovery
Brazilian Journal of Chemical Engineering, 2015Co-Authors: Keshak Babu, N K Maurya, Ajay Mandal, V K SaxenaAbstract:Attention has been given to reduce the cost of surfactant by using castor Oil as an alternative natural source of feedstock. A new surfactant, sodium methyl ester sulfonate (SMES) was synthesised using ricinoleic acid methyl ester, which is obtained from castor Oil, for Enhanced Oil Recovery in petroleum industries. The performance of SMES was studied by measuring the surface tension with and without sodium chloride and its thermal stability at reservoir temperature. SMES exhibited good surface activity, reducing the surface tension of surfactant solution up to 38.4 mN/m and 27.6 mN/m without and with NaCl, respectively. During the thermal analysis of SMES, a 31.2% mass loss was observed from 70 ˚C to 500 ˚C. The phase behavior of the cosurfactant/SMES-Oil-water system plays a key role in interpreting the performance of Enhanced Oil Recovery by microemulsion techniques. Flooding experiments were performed using a 0.5 pore volume of synthesized SMES solutions at three different concentrations. In each case chase water was used to maintain the pressure gradient. The additional recoveries in surfactant flooding were found to be 24.53%, 26.04% and 27.31% for 0.5, 0.6 and 0.7 mass% of surfactant solutions, respectively.

opportunities for using anthropogenic co2 for Enhanced Oil Recovery and co2 storage
Energy & Fuels, 2013Co-Authors: Michael Godec, Vello Kuuskraa, Phil DipietroAbstract:CO2-Enhanced Oil Recovery (CO2-EOR) has emerged as a major option for productively using CO2 emissions captured from electric power and other industrial facilities as part of carbon capture and storage (CCS) operations. Not only can depleting Oil fields provide secure, well-characterized sites for storing CO2, such fields can also provide a source of revenues to offset the costs of capturing CO2 by producing incremental Oil. This paper draws significantly on work by Advanced Resources International, Inc. (ARI), sponsored by the United States Department of Energy’s National Energy Technology Laboratory (U.S. DOE/NETL) [Advanced Resources International, Inc. (ARI). Improving Domestic Energy Security and Lowering CO2 Emissions with “Next Generation” CO2-Enhanced Oil Recovery; ARI: Arlington, VA, 2011; http://www.netl.doe.gov/energy-analyses/pubs/storing%20co2%20w%20eor_final.pdf] and the International Energy Agency Greenhouse Gas Research and Development Programme (IEAGHG) [Advanced Resources International, ...

co2 utilization from next generation co2 Enhanced Oil Recovery technology
Energy Procedia, 2013Co-Authors: Vello Kuuskraa, Michael Godec, Phil DipietroAbstract:Abstract CO 2 -Enhanced Oil Recovery (CO 2 -EOR) has emerged as a major option for productively utilizing CO 2 emissions captured from electric power and other industrial plants. Not only can Oil fields provide secure, well characterized sites for storing CO 2 , they can also provide revenues to offset the costs of capturing CO 2 . Though utilization of captured CO 2 emissions for Enhanced Oil Recovery has been underway for some time, further advances in CO 2 -EOR technology could significantly improve the technology's applicability as a revenue generator for CO 2 capture and a large-scale CO 2 storage option. With application of “next generation” CO 2 -EOR technologies in geologically favorable settings, the volume of CO 2 stored could exceed the CO 2 content of the Oil produced. The paper draws significantly on the recently completed report sponsored by the U.S. Department of Energy, National Energy Technology Laboratory (U.S. DOE/NETL) and prepared by Advanced Resources International entitled, “Improving Domestic Energy Security and Lowering CO 2 Emissions with “Next Generation” CO 2 -EOR”. The paper introduces the feasibility of applying “next generation” CO 2 -EOR technologies to new, challenging areas, such as to residual Oil zones (ROZs) below and beyond the structural confinement of existing Oil fields and to offshore Oil fields. The paper provides a case study that tracks the performance and the economics of CO 2 -EOR in the Permian Basin of West Texas. While much of the information in the paper is drawn from the CO 2 -EOR experiences in North American Oil fields, the paper also examines the CO 2 utilization and storage potential from applying “next generation” CO 2 -EOR technology to the large Oil fields of the world, drawing on extensions of work performed by Advanced Resources International for the IEA Greenhouse Gas R&D Programme. The paper concludes with two key messages. First, with application of “next generation” technologies to a broader set of Oil resources, the market for utilization of CO 2 for Enhanced Oil Recovery is much larger than previously assumed. Second, the revenues from the sale of captured CO 2 emissions, along with research that reduces the costs of CO 2 capture, can greatly accelerate the time when CCS (now CCUS) can be applied at wide scale.
